Abstract

L-star is a system for building software systems. The design of L-star stresses features not found in many other implementation languages or systems: it is interactive rather than compiler based, it has a symbol manipulation language embedded in it, it is highly extensible, and it allows for total accessibility to both the underlying hardware and the L-star system itself. This paper describes the design philosophy of L-star, the mechanisms used to implement it, the experiences had in using it, and some unresolved issues it still presents.
